A spokesman for Maine State Police said Rashad Robinson, 35, of South Paris was getting a haircut at Major Cuts in Lewiston when he was stabbed in the stomach and chest. He then staggered out of the barber shop onto the sidewalk and collapsed.
Police have arrested and charged Michael Barrucci, 23, of Otisfield with elevated aggravated assault.
Officials also said Barrucci is dating Robinson's estranged wife, who was also at the barber shop at the time of the stabbing.
Robinson had to go through emergency surgery at Central Maine Medical Center and police continue to monitor his condition.
